We propose an ultracompact broadband polarization beam splitter (PBS) based on a combined hybrid plasmonic waveguide (HPW). The proposed PBS separates transverse-electric (TE) and transverse-magnetic (TM) modes using a bent lower HPW with vertical nanoscale gaps and a straight upper HPW with a horizontal nanoscale gap, respectively, without relying on an additional coupling region. Ultrashort broadband polarization beam splitter based on a Jan 20, 2016 · We propose an ultracompact broadband polarization beam splitter (PBS) based on a combined hybrid plasmonic waveguide (HPW). The proposed PBS separates transverse-electric (TE) and transverse Terahertz polarization beam splitter based on two photonic In this work, we propose a novel compact terahertz polarization beam splitter by combining a photonic crystal linear defect waveguide and two photonic crystal cavities. In the proposed scheme, the polarization beam splitter consists of two photonic crystal cavities region with an internal photonic crystal section inside.
